Roof and backfill is done. Now for the deck and windows and then the inside renovations can start. I am sick of this project and we're only half way done. I don't think we will get the outside paint done before it starts snowing

The valleys in the roof took a bit of measuring, and then some more measuring. The black lining is to keep the condensation off the roof sheets and the "strapping" is so that there is air movement under the tin to help minimize condensation

Nothing special (primer and top coat) but temperature needs to be +5C. I think I missed my window of opportunity. They are predicting snow for next week and after that minus temperatures . This sets me back almost 5 months, but not getting the outside paint done is not the end of the world.

Low working temperatures have implications for certain construction materials.Concrete for example must be mixed with hot to boiling water to prevent it from freezing solid before it achieves initial set.They generally also use 'rapid hardening cement' in US and Canada for the same reason.

If concrete freezes before it sets, it will not reach its design structural strengthand may crumble under load when it unfreezes again.Conversely, if you allow wet mass concrete to get too hot during the initial set,it will boil and form voids in the concrete with resulting lowered structural strength.

I would think that the paint has similar challenges in low temperatures.

friends of mine worked at Fort McMurray on the shale sands, pouring concrete at stupid low temps but with lots of chemical additives

Thanks Woody1 and Oubones.It took us 11 years to make the decision. We never came here to stay, but life happens! We were worried that if we ever get a prime minister like Trump, we could be kicked out of the country by the stroke of a pen, so better to have full status. But this country has been very good to us and we are very grateful for all we have here. Friday will be a bitter sweet day, a funeral and a celebration all at once. It is funny what difference a piece of paper can make.
